Merging two frames using V4L2 API?

[byunggukchoi]

I've been trying to merge two images captured from two uvc cameras attached on IMX6Q Sabre Auto board.

When merging at application level, the performance was very poor.  So I'm trying to do that using V4L2 API.

Is there a way to merge two frames directly using V4L2 at kernel level? It'll very helpful to me.

Thanks in advance.

Hi ByungGuk,

There is support for V4L2 in NXP Linux BSPs and it is described in Chapter Video for Linux Two (V4L2) Driver, in Linux Manual. However such implement is not evaluated
